JD Robot Connection Issue

Thanks - let’s troubleshoot this stepbystep. Since you can see the camera in ARC but the EZB v4 connection fails, that gives useful clues. Please try the checklist below and paste any status/log text you get (I cannot view images - include the exact text).

1. Quick checks (most common causes)

• Confirm how you’re connecting the EZB: WiFi (IP) or USB/COM?
• Make sure the EZB Connection skill is using the same connection index you expect (use index 0 if you only have one controller).
• Disable any 3rdparty antivirus/firewall temporarily (Avast, McAfee, Norton are frequent culprits). See: https://synthiam.com/Support/troubleshooting/Troubleshoot-WiFi-Connections
• Verify ARC version is current: https://synthiam.com/Products/ARC

2. Get basic status from ARC (run these in a JavaScript script or the Script Console)

• Get the configured address for connection index 0:

var addr = controlCommand("Connection","GetAddress",0);
print("Address: " + addr);

• Check whether ARC thinks the EZB is connected:

var status = controlCommand("Connection","GetStatus",0);
print("Connected?: " + status);

Copy/paste the printed values here.

3. Test TCP reachability to the EZB

• If you connect by IP, try a telnet / port test from your PC to the EZB (replace 192.168.1.1 with your EZB IP): Windows CMD:

telnet 192.168.1.1 23

PowerShell:

Test-NetConnection -ComputerName 192.168.1.1 -Port 23

If port 23 is filtered/blocked the test will fail. Paste the Test-NetConnection output if available.

4. Use the Connection Diagnostic skill (verbose logs)

• Add Project -> Add robot skill -> General -> Connection Diagnostic
• In that skill: press Ping EZB and then Copy Log to Clipboard
• Paste the log text here (do not post screenshots - paste the exact text)

• EZB firmwares / hardware overview: https://synthiam.com/Support/Hardware/Hardware-Overview

5. Firmware / Mode checks

• Camera working suggests the EZB’s IP/HTTP is reachable. The connection channel uses a TCP socket/protocol the firewall or firmware may block. Try:
  • Reboot EZB and PC.
  • If the EZB is in "client" mode (connects to ARC), ensure ARC’s TCP EZB Server (if used) is enabled. If EZB is in AP mode, ensure your PC is on the EZB’s WiFi or they’re on the same router/subnet.
  • If firmware mismatch is suspected, consider reflashing the EZB firmware: https://synthiam.com/Support/Hardware/Hardware-Overview

6. Power & wiring

• Confirm JD’s power is supplying the EZB properly. Brownouts or low voltage can make the EZB appear to boot (camera works) but fail protocol services. Tell me what battery/how you power JD.

7. Extra checks if using USB/COM

• If using COM: open Device Manager, confirm COM port number. In the EZB Connection skill choose that COM and the correct baud. If another app (Putty, serial monitor) is using that COM, close it.

What I need from you now

1. Are you connecting by WiFi (IP) or USB/COM? What exact address or COM port are you using?
2. Output of the two ControlCommand prints (Address & Connected?) from step 2.
3. Result of TestNetConnection or telnet (if using IP).
4. Paste the Connection Diagnostic log text if you ran it.
5. ARC version and Windows version.
6. Any exact error message shown in the ARC status area - paste the text.

I’ll walk through the results and give the next targeted steps (firewall rules, port tests, or firmware updates). Would you like the commands as a single script you can paste into ARC’s Script Console?
